Two brothers grew up together in the countryside, unaware that the elder brother had been placed in their home by his aunt because she was struggling financially. When the brothers grew up, their mother, encouraged by their maternal uncle, decided to divide the family property. To benefit his biological nephew, the younger brother, the uncle rigged a lot-drawing process so that the younger brother would get the new house. After initially making money by trusting his wife's younger brother with an investment, the younger brother fell victim to a pig-butchering scam. He mortgaged his house and dragged fellow villagers into the scheme, eventually fleeing with his wife to escape their debts. Meanwhile, the aunt returned wealthy and searched for her son. The uncle came up with a plan for the younger brother to impersonate him and obtain money to repay his debts. After generously giving them money, the aunt discovered the truth and angrily confronted the younger brother's biological mother. Grateful for the adoptive mother's years of care, the loyal elder brother is torn between two sides when his biological mother forces him to choose one of them.
